C The following will probably require the chain rule. 1. esin(2) 2. log( cos(a) ) 3. e-72/2 4. xx 5. sin(?) 6. x sin(?) 7. x2 sin(?) 8. e-1/22 9. 10* 10. sin(x) where "sin" is the function with period 360 rather than 27, that is, it "expects its input in degrees". 11. log10(2) 12. log(sec(x) + tan(x)) (what is the simplest expression you can find for the derivative here?)
